Image acquisition and processing equipment and method, vehicle monitoring and recording system

Abstract

The invention relates to an image obtaining and processing device and a method thereof, and a vehicle supervising and recording system. The image obtaining and processing device comprises: an imaging unit which is used for photographing video images within a supervised region and generating corresponding analog video stream, an analog digital transforming unit which is used for transforming the analog video stream into digital video stream, a video triggering unit which is used for analyzing the digital video stream and generating a video triggering signal when a vehicle is detected, a snapping unit which is used for obtaining a current video image from the digital video stream after receiving a triggering signal which comprises the video triggering signal output by the video triggering unit, an information obtaining unit which is used for processing the video image obtained by the snapping unit so as to obtain vehicle information from the image. The image obtaining and processing device realizes the integration of the obtaining and real-time processing of the image, thereby simplifying the structure of the vehicle detecting and recording system and reducing the installment complexity of the system.

Description

technical field [0001] The invention relates to the field of traffic control systems, in particular to an image acquisition and processing device and method, and a vehicle monitoring and recording system using the image acquisition and processing device and method. Background technique [0002] The vehicle monitoring and recording system plays an important role in traffic monitoring, traffic management, and social security. It plays an important role in combating speeding and illegal acts, and deterring criminals. Assisting in the inspection of vehicles for deployment and control, greatly improving the safe driving environment, and at the same time serving the social security management. [0003] At present, the vehicle monitoring and recording system on the market uses a camera installed on the driveway to take pictures of the vehicle, and then transmits the captured analog image signal to the indoor industrial computer or image processing equipment through the data communi...

AI Technical Summary

Problems solved by technology

[0006] The camera needs to be connected to the industrial computer or image processing equipment through an embedded board or image acquisition card, which makes the system structure more complex, and the installation complexity of indoor equipment is also high;

[0007] The camera only has a simple imaging function, and the transmitted video signals are basically analog signals, not only the transmission speed is slow, but also consumes a lot of network resources and storage resources;
